thanks for the clarification.  i thought that might be the case.  i
take it as w/ many perl things, the script was a quick hack (just
observing), as you use "my" for some variables and not others, and
some variables are not used at all.


off-topic perl hack note: i think you can use a block w/ local($/), to
get the effect you like:

{
  local($/);

  # do what you like here

}

# out here $/ is restored

but, may be you knew that already ;-)
